I was looking a early hoehn tuner that I have had milled out to fit my barrel and noticed that in the opening between the hex screws that are screwed down to hold the tuner to the barrel and the foward part of the tuner there is a gap that runs across the tuner from left to right. when the barrel is seated down on the tuner you can see the barrel. In this gap there was some metal shavings that came from the milling job that looked like a silver ribbon of metal . I took a tooth pick and pushed the ribbon down inside the tuner where it fell out on my work bench. Are these shavings a problem and does the inside of the tuner need polishing . If polished to smooth the inside of the tuner will it cause the tuner not to fit as tight as it should. hope you understand what I am asking. Thanks for any help.garrisone.

I would wash the inside with some spray cleaner and mount it just the way it is. If you polish it you will remove some of the metal thus makeing it larger. All of mine have looked rough when I mounted them besides it might help it grip the barrel better.

Garrisone:

I have five Harrell Tuners (same as Hoehn) and all my tuners are smooth inside. The last one I bought was rough, almost like threads, and when I called Lynnwood Harrell, he said that it should not have left the shop that way and to send it back and he would polish it.. My smooth tuners do not have any problem gripping the barrell..

Just for your info..

is the Harrell tuner made by the same company that makes the powder measures?

garrison,

when you are saying:

when the barrel is seated down on the tuner you can see the barrel.
combined with what you say later:

I took a tooth pick and pushed the ribbon down inside the tuner where it fell out on my work bench.

and I hope I'm reading this wrong because, what it makes it sound like is that you are not only seeing the barrel through that gap, but the muzzle as well, and that's not right!

This would definitely mean that your tuner has either loosened up and is working its way off your barrel, or whoever did the fitting of your tuner did not bore it deep enough for the tuner to be properly seated against your muzzle and needs to be not only cleaned, but rebored deep enough for you muzzle to seat against that little ledge that's built into all new tuners showing exactly how deep the muzzle should be positioned.

Either way, if I were you I would first loosen the two screws holding the tuner in place, then try to push my tuner further onto the barrel to see if it had simply worked its way down the barrel some, or needs to be rebored. Then, I would take it off, fully clean out all the debris, and either slide it back onto the barrel if it was simply a matter of it being loose, or, have it refitted if it wasn't.

Joe Haller,

Same people!

It is the same. The only change now is that they are threaded for a bloob tube and any of a series of weights although niether required.

Are the tuners turned to fit the barrel diameter before or after the slot is milled in the bottom of the tuner? Seems that boring to size after the cut might cause an "out-of round" hole. (?)

Boring is last. You can buy an unbored one and have it done by you're guy. The material is thick enough and should bore true, they've always been this way, no problems. It must, however, be done for a snug fit, it's not uncommon to see them done oversize and all the slack taken up with the small screws...not the way to have proper fit.

Joe,

All bore sizing is done after both the cross and clamping cuts are made as those two are done during assembly, while the sizing is done by the gunsmith.
